Jason Steele felt Rovers deserved at least a point from Saturday's match with Fulham.
The Rovers goalkeeper felt it was a much improved display against the in-form Londoners until the visitors snatched the victory deep into injury time.
Steele believes that if the side can repeat the way they played against Fulham, then the wins will arrive sooner rather than later.
"It is a sickener without a doubt," Steele told Radio Rovers. "It had a draw written all over it. It was a match between two decent teams.
"From our point of view, although we are disappointed, it was a hell of a lot better. We looked solid, strong, concentrated, and we looked dangerous at times on the break.
"I thought we were good, but in the end it is a sucker-punch, it was smash and grab.
"We knew playing Fulham that they do dominate the ball, we defended well, we held our lines, we were narrow and compact and limited them to few opportunities.
"We are all just bitterly disappointed not to have taken something away from the game but if we keep playing like that then we will be alright."
The first team are back in action away at QPR after the international break, whilst the development squad take part in the new-look Checkatrade Trophy this Tuesday night at Fulham.
